The unmanned vehicle and vessel attitude sensor is a high-performance, cost-effective Attitude and Heading Reference System (AHRS). It is specifically designed for unmanned ground vehicles (UGV), unmanned surface vehicles (USV), underwater robots (ROV/AUV), and other mobile robotic platforms, capable of providing real-time, accurate three-dimensional attitude and heading data in complex dynamic environments, serving as the core sensor for precise control, autonomous navigation, and stable operation.
Core Product Advantages
-
Outstanding Dynamic Performance: Utilizing advanced sensor fusion algorithms, it ensures roll/pitch angle accuracy better than 0.8° even under severe shaking conditions, laying the foundation for stable control of unmanned platforms in scenarios such as waves and rugged terrain.
-
Superior Heading Stability (specific to TM362-P model): Equipped with a higher precision Z-axis gyroscope, significantly improving yaw angle drift. In pure inertial mode, the heading angle error is only 1.7° every 25 minutes, better than the standard version’s 2.6°, providing a more reliable heading reference for long-duration missions.
-
Strong Anti-Interference Capability: Built-in adaptive magnetic field filter effectively compensates for magnetic interference in the environment, still outputting reliable heading information even in certain metallic interference scenarios, enhancing usability in complex electromagnetic environments.
-
Industrial-Grade Robust Design: The main body has a protection level of IP67, offering excellent dust and splash water resistance. A wide operating temperature range (-20°C ~ +80°C) and good vibration resistance ensure stable operation in harsh outdoor and aquatic environments.
-
Convenient Integration and Debugging: Provides various industrial standard interfaces such as UART, CAN, USB, and comes with graphical ImuAssistant configuration software for quick sensor configuration, data visualization, calibration, and data recording, greatly shortening the development and integration cycle.
Typical Application Scenarios
-
Unmanned Surface Vehicles (USV): Maintaining water surface tracks, attitude stability control, marine surveying.
-
Underwater Robots (ROV/AUV): Underwater attitude monitoring, navigation control, equipment orientation.
-
Unmanned Ground Vehicles (UGV): Terrain surveying, platform leveling, autonomous driving attitude feedback.
-
Robotics and Automation: Robotic arm attitude control, AGV navigation, platform stability monitoring.
